This and Fig. 16 shows in face andedge views, revalve comprises a two-part casing having aspectively, thevalve-seating spring. valve-seat 38 provided With'an annular open- Thetruck of the channeler is herein deing 39. This opening 39 in thevalve-seat is noted by 1', its wheels by 2, and the trackopened andclosed by an annular valve 40, the I rails by 3. The channeler-cylinder5is'mountoutward movement of which valve is limited by acentrally-arranged retaining-plate 41,

ed on a shell 6, which is longitudinally adjusthaving peripheral lugs'42 overlapping the valve at intervals. This valve 40 is of angularconstruction in cross-section, and it is held yieldingly closed by adisk spring 43, the fingers 44 of which engage with the said valve. Abolt 45 and nut 46 serve to hold the retaining-plate 41 and spring 43 inposition on the valve-seat 38. For admitting air from the exterior tothe interior of the presser-cylinder intermediate its ends I provideanother one-way valve 47, quite similar in construction to the valve 37,which valve in this instance acts as an induction-valve. This valve 47is so arranged that it will alternately admit air to the spaces aboveand below the airpresser piston 48 as the piston is reciprocated. Thispiston 48 is provided with a trunk 49. which is fitted to slide in theinterior of the hollow body 50, which connects the lower head 25 withthe crank-casing 51. This pistontrunk 49 is connected to the crank 52 ofthe shaft 14 by a pit-man-rod 53.

The piston of the channeler is denoted by 54, and it is provided withthe usual depending piston -rod 55, to which the tool (not shown herein)may be secured. In addition thereto the piston 54 is provided with anupwardly-extended plunger 56, which is fitted to slide in the bore 57 ofa smaller cylinder 58, which surmounts the top head 18 of thechanneler-cylinder 5. A short pipe 59 connects a port 60, opening intothe upper part of the cylinder-chamber, with a port 61, opening into thebore 57. This port 61 is preferably so arranged that open communicationwill be established between the upper part of the cylinder-chamber andthe bore when the piston 54 is near the limit of its downward movement.

In operation the channeler-tool may be adjusted along the truck to anydesired point, and asit is being adjusted to this point the presser andmotor will be turned on their support, thus enabling me to use theshortest possible length of pipe through which the air is compelled topass between the presser-cylinder and channeler-cylinder. Furthermore,the presser and motor may be adjusted bodily toward and away from thechanneler by shifting their swivel-frame 10 on the base-plate 8. In theaccompanying drawings the motor and presser are shown as adjusted totheir nearest point to the channeler. When the plug 27 of the three-wayvalve is turned into position to open communication between the lowerparts of the presser and channeler-cylinder chambers, the reciprocationof the piston 48 will impart afull downstroke to the channeler-piston.The upstroke of the channeler-piston, however, will be cushioned by thecompression of the air in the bore 57 of the cylinder 58 after theplunger 56 cuts 011' the port 61. The valve 47 of the presser-cylinderis so arranged that whenever the pressure on either side of thepresser-piston falls below that of the external atmosphere the valvewill admit air thereto. It will thus be seen that as the presser-pistonis reciprocated the columns of air will be moved back and forth in thepipes 16 and 19 for reciprocating the piston 54 to obtain the fulleffectof the tool in the rock upon which it is operated. When the plug27 is turned into position to close communication.between the lower endof the channeler-cylinder chamber and the lower end of thepresser-cylinder chamber and the lower end of the presser-cylinderchamber is opened to the variable-pressure receivers 35 36 in the pipe34 as the channeler piston is forced downwardly because of the admissionof air from the top of the presser-cylinder chamber to the top of thechanneler-cylinder chamber, the air in the bottom ofthechanneler-cylinder chamber and in the pipe 19 will be compressed, as ithas no way of escape, thus pre venting the piston 54 from performing acomplete downward stroke. Ordinarily when working under these conditionsthe air would leak away from beneath the channeler-piston and thechanneler-piston would finally strike the bottom head. This isprevented, for the reason that when the pressure in the pipe 19 fallsbelow the receiver-pressure in the pipe 34 the valve 37 willautomatically open, and I thus permit the air from the receiver-pipe 34to escape into the pipe 19 and cause it to retain its cushioning effect.When the plug 27 of the three-way valve is turned into position to openthe under side of the presser-cylinder chamber to the atmosphere throughthe branch 22, it will be seen that communication to the variablereceiver-pipe 34 is closed, and also communication through the pipe 19is closed. In this position the downward movement is imparted to thechanneler-piston against compression in the pipe 19 without permittingthe recharging of the variable re. ceivers when the presser-piston movesdownwardly. This is done when the receivers 35 36 are fully charged andit is desired to take the load ofl from the presser-piston during itsdownward movement.

It will be seen by the arrangement which I have provided for holding thevalve-plug 27 in its difierent adjustments all danger of causing the airunderneath the rapidly-reciproeating presser piston being dischargedthrough a small orifice, and thereby causing the piston to use anabnormal power or impart dangerous strains to the the working parts, isobviated.

The construction of the valves 37 and 47 is such as to permit a veryfree passage of the air through the valves with a slight movement of thesame.

It is evident that various changes might be resorted to in theconstruction, form, and arrangement of the several parts withoutdeparting from the spirit and scope of my invention. Hence I do not wishto limit myself strictly to the construction herein set forth; but

What I claim as my invention is- 1.
